A method may include receiving, by a computing device associated with a user, a message from an origination source and receiving, by the computing device, an audio input. The method may also include determining, by the computing device and based at least in part on the audio input and contextual information, a probability that the user intends to send a response message to the origination source. The method may further include, responsive to determining that the probability the user intends to send the response message to the origination source satisfies a threshold probability, determining, by the computing device, that the user intends to send the response message to the origination source. The method may also include, responsive to determining that the user intends to send the response message to the origination source, generating, by the computing device and based on the audio input, the response message, and sending, by the computing device, the response message to the origination source.
